This “guide” started as pretty basic article and turned into a slightly more expanded guide on electronic design and programming techniques for Netduino. To knowledgeable users, some topics may seem gone too much in depth and detail even for “basic” subjects. However, the aim was to provide beginners with knowledge and confidence they need to become advanced enough so that to design successful microcontroller projects by themselves. Additionally, it is always a good idea to understand how things work, even when we can achieve the results using LEGO approach with shields.
